[FEATURE]: Add support to generate developer documentation from Doxygen comments

[evan-palmer]

Is your feature request related to a problem? Please describe

The implementation has been documented using Doxygen. To make it easier for new users and developers to get started with contributing to the project, it would be helpful to provide support for generating a site from the comments.

Describe the solution you'd like

Add the necessary files to generate a site from the doxygen comments. It will also be necessary to document the steps to generate this documentation.

Describe alternatives you've considered

If possible, it would be much more useful to generate this documentation as part of the user documentation (see Issue #14). However, if this is not possible, then a separate site may be used.

Implementation Ideas

Create the respective Doxygen configuration files needed to build the site.
